“The inquiry is frequently made of me, 'Wherein do you differ from others in your religious views?' In reality and essence we do not differ so far in our religious views, but that we could all drink into one principle of love. One of the grand fundamental principles of ‘Mormonism’ is to receive truth, let it come from whence it may.” 

Joseph Smith, quoted in History of the Church of Jesus Christ of Latter-day Saints, 2nded. 

(Salt Lake City: Deseret News Press, 1949), 5:499.
